Abstract: A process and a system thereof include apparatuses for developing multi-component vapor mixture by heating of solution of reactants comprising one or more of diphenols, or diphenol derivatives, and an organic compound. Upon reacting in a vapor state in presence of a catalyst with diphenols, or diphenol derivatives, the organic compound produces a monoalkyl ether of a dihydric phenolic compound. The entire solution of reactants completely transforms into a super-heated multi-component vapor using heaters without the use of thin film evaporator. The complete transformation of the entire solution of the reactants in to super-heated multicomponent vapor is achieved by heating the entire solution firstly by a pre-heater followed by further heating by a super-heater. The unevaporated or condensed high boilers and tar are removed to drain. The superheated vapor is subjected to vapor phase reaction mediated by catalyst to get monoalkyl ether of a dihydric phenolic compound.
